Why Docker changes everything

A year ago hardly anyone had heard of Docker, a small open source project using some arcane features of the Unix operating system. Going into 2015 Docker, or more accurately container-based deployment, is suddenly on every corporate IT roadmap.

What is a Docker container? How is it different from a virtual machine? Why does it matter? And more importantly why should you care about it?

As physical servers give way to virtual machines, and virtual machines give way to cloud infrastructure, containers may be the magic dust that enables your organisation to make the best use of its existing hardware investment and pave the way to Continuous Delivery.

In this talk, Dan North describes the landscape that container-based deployment is shaping, and gives you some pointers to tools, technologies and resources so you can start exploring it for yourself.
